Shrooms for the first time
Don't worry about your eyes being red, worry about looking like an escapee from the local lunatic assylum. Like xblizzx said, "dont go around others on shrooms " . Its not like weed where you can just act straight around someone and then giggle when they walk away. It ain't gonna make any difference what color your eyes are if you go up to your mom or pop babbling incoherently about your fingers stretching or the walls breathing.
Get together with some friends and go someplace cool, without a lot of other people (unless they're shroomin too) and make sure you have a good 4-5 hours of uninterupted time. Whatever you do don't just go home and eat them by yourself in your room.
Shrooms for the first time
And above all, let it be known there is a fountain that was not built by the hands of men.
